3. COLUMN CHART 3

4. PIE CHART 4

5. LINE CHART 5

6. TRENDLINE Linear: with linear data sets Logarithmic: when data increases or decreases quickly and then levels out. Polynomial: when data fluctuates. Power: data that increases at a specific rate Exponential: when data values rise or fall at increasingly higher rates Moving Average: smoothes out fluctuations in data to show a pattern or trend more clearly 6

7. TRENDLINE R-Squared Value: –Coefficient of determination –Measure the goodness of the trendline to the data. –R 2 = 1, Perfect fit 7

8. SPARKLINES Visual representation of the data in worksheet cell. 8

9. PIVOTCHART AND PIVOTTABLE PivotTable –Used to extract more meaningful information from the data. –Interactive table. –Quickly summarizes numeric data. PivotChart –Virtual representation of a pivot table. 9

10. CORRELATION ANALYSIS [-1,+1] –+1: Perfect positive correlation – -1: Perfect negative correlation – 0: NO correlation CORREL(array1, array2) 10
